Introduction
Evidence is any information gathered at the scene of a crime that may be relevant to a criminal investigation. There are different types of evidence that varies from Paperwork, Photographs, DNA, Finger prints; etc... These different kinds of evidence also require different types of opinions and explanations. Analyzing DNA is the best way to get your evidence. Every effort must be made to ensure that evidence is not lost, damaged, or contaminated. Evidence has many different roles in the investigation of a crime. It can link
a suspect to a crime scene if (example) a footprint matching the shoe of the suspect is found. Evidence can also eliminate a suspect. If the shoe size of the suspect does not match that of footprint evidence, then those footprints cannot tie that suspect to the crime scene. Evidence could also back up or contradict a witness statement that can help guide the police in further investigations. Evidence such as DNA or fingerprints is also valuable in providing an accurate ID of the suspect (s)
Paperwork
Paperwork can be both reliable, and none reliable. If the source is not legible and you cannot read it or if it was a written statement that use short hand and one can’t understand; example using short hand words such as; wrk for the word work or abt for the word it can cause a confusion of understanding. Paperwork can be a reliable source of evidence because you can always refer to your paperwork when trying to solve a case or you can add new material to these files. Paper work can consist of helpful photos copies, criminal sketches, pictures of a criminal and their known whereabouts.
Photographs
Crime scene photography is a very reliable source of evidence because photographs are used from a perspective point of view. Observation is the main key to taking these accurate photos. When you are using these photographs it’s always a good idea to compare the similarities, differences, and their reliability. These photos are taken in many different angles and overviews to insure quality photographes of a crimes scene.
Additional Evidence
Additional Evidence such as; Fingerprints, bloodstains, trace evidence, and DNA evidence are the most important evidence in the criminal justice it is the most accurate and physical evidence that you have because it deals with direct collection and proper analysis.
